OL-16601-01
Workaround: Before downgrading to the Cisco NX-OS 4.0(1a)N1(1) release, remove rules from
the roles configuration such that a role does not have more than 67 rules.
CSCsv55655
Symptom: The Cisco Nexus 5000 Series switch Ethernet port is configured in the 1 G mode of
operation using the speed 1000 command. It does not advertise and auto-negotiate the flow control
configuration. As a result, the link peer does not learn about the capabilities of the Nexus 5000
Series switches and does not enable flow control at its end.
Workaround: Disable auto-negotiation on the link peer and enable flow control for flow control to
work over the link.
CSCsw39639
Symptom: When a rule that refers to a specific interface name (Ethernet 1/1) is entered in the role
definition CLI, the command could hang. Type Ctrl-C to return to the CLI prompt.
Workaround: Do not configure rules that refer to specific interfaces in the role definition CLI.
CSCsy09062
Symptom: This is an open caveat in 4.0(0)N1(2a) and 4.0(1a)N1(1) releases. After an upgrade or
downgrade if the show startup security command is issued before performing a copy
running-config startup-config, the security process could crash.
Workaround: You can avoid a core dump by issuing a copy running-config startup-config
command after an upgrade or downgrade and before issuing the show startup <feature> command.
CSCsy08516
Symptom: This is an open caveat in 4.0(0)N1(2a) and 4.0(1a)N1(1) releases. After an upgrade or a
downgrade and when the system comes up, users are assigned a network-operator role by default.
Workaround: To avoid the problem, reload the switch after an upgrade or a downgrade and after
the system comes up. You can then perform the copy running-config startup-config operation to
save the correct configuration.
CSCsy37432
Symptom: This is an open caveat in the Cisco NX-OS 4.0(0)N1(2a) release. On the 4.0(0)N1(2a)
release if an RBAC role has more than 35 rules configured, show running-config and copy
running-config cause the vshd process to core dump.
Workaround: Before downgrading to the Cisco NX-OS 4.0(0)N1(2a) release, remove rules from
the roles configuration such that a role does not have more than 35 rules.
CSCsy53275
Symptom: This is an open caveat in the Cisco NX-OS4.0(0)N1(2a) release. If there are 20 RBAC
roles configured with 20 rules each, the RBAC feature becomes non-functional.
Workaround: Do not configure more than 20 rules in each role. The feature works fine if the
numbers of rules are limited to 10 per role.
